Lambda Sensor Advice?

Hello, I was wondering if someone can help me. Im 95 impreza has started to misfire/ flat spot when the engine is hot.

I have noticed it seems to do it seems to do it when i come off the motorway and come to a stop. Then when i pull away thats when it seems to do it. The engine light doesn't come on and if you just rev her when you stop its fine but she doesn't always do it!

I asked someone to drive her to see what he thought as i dont know much about these cars and any advice is really greatfull. He said it might be the lambda sensor because she also failed on the emissions when she went for mot last month.

I've changed the plugs & fuel filter.

I've been on the net and looked up these sensors and I dont know which one i need because it asks how many wires mine has or a part number I have no idea. Anyone know?

Plus where should i order it from, i've seen 2 websites one is called just lambda and the other is cats to go, anyone bought from either of these sites and are they a good make? OR is there somewhere else?

Thanks for your help!!!

If its a turbo I would say it could be the maf sensor if its not a turbo could be the (oxygen sensor) lamba sensor
